Light as a Feather

There are a total of 15 Phoenix Feathers in God of War Ascension. Finding all of them will max out your magic and earn you the silver trophy "Light as a Feather". Everytime you find 5 Phoenix Feathers your magic increases. The feathers are in white treasure chests. However, there are far more chests with Phoenix Feathers than you need. So you can miss some of them and still earn the trophy. After getting all 15 Phoenix Feathers you will be rewarded with red orbs everytime you open a white chest.
